Spin-3/2 physics of semiconductor hole nanowires: Valence-band mixing and tunable interplay between bulk-material and orbital bound-state spin splittings
D. Csontos, P. Brusheim, U. Zuelicke +1
We present a detailed theoretical study of the electronic spectrum and Zeeman splitting in hole quantum wires. The spin-3/2 character of the topmost bulk-valence-band states result…
Lande-like formula for the g factors of hole-nanowire subband edges
D. Csontos, U. Zülicke, P. Brusheim +1
We have analyzed theoretically the Zeeman splitting of hole-quantum-wire subband edges. As is typical for any bound state, their g factor depends on both an intrinsic g factor of t…
Tailoring hole spin splitting and polarization in nanowires
D. Csontos, U. Zuelicke
Spin splitting in p-type semiconductor nanowires is strongly affected by the interplay between quantum confinement and spin-orbit coupling in the valence band. The latter's particu…
Large variations in the hole spin splitting of quantum-wire subband edges
D. Csontos, U. Zuelicke
We study Zeeman splitting of zone-center subband edges in a cylindrical hole wire subject to a magnetic field parallel to its axis. The g-factor turns out to fluctuate strongly as…
Strong spin relaxation length dependence on electric field gradients
Dan Csontos, Sergio E. Ulloa
We discuss the influence of electrical effects on spin transport, and in particular the propagation and relaxation of spin polarized electrons in the presence of inhomogeneous elec…
Spin polarization control by electric field gradients
Dan Csontos, Sergio E. Ulloa
We show that the propagation of spin polarized carriers may be dramatically affected by {\em inhomogeneous} electric fields. Surprisingly, the spin diffusion length is found to str…
